SCYTHE SNATH.

Application filed April 3,

An object of this invention is to provide improved means for detachably connecting a scythe snath and blade.

A further object 01 this invention is to provide improved means for adjustably connecting a scythe snath and blade.

A further object of this invention is to provide an improved construction for a scythe snath.

A further object of this invention is to provide improved means for mounting nibs or handles on a scythe snath.

My invention consists in the construction, arrangement and combination of elements hereinafter set forth, pointed out in the claims and illustrated by the accompanying drawing, in which-- Figure 1 is a perspective showing the preferred forms of my improved device assembled as required for practical use. Figure 2 is a cross-section of the device on the indicated line 2-2 of Figure 1, on an enlarged scale. Figure 3 is a cross-section of the device on the indicated line 3-3 of Fig ure 1, also on an enlarged scale. Figure 4 is a perspective showing an adjusting plate and means employed to connect the same to a sn-ath. Figure 5 is aperspective of the inner end portion of a blade, showing the means employed to connect it to the adjusting plate.

Figure 6 is a perspectiveshowing a modified form of a portion of a scythe snath preterably made of metal of channel torm in cross-section together withmeans for con necting a snath thereto. Figure 7 is a crosssection showing the arrangement and means for connecting a nib or handle to the angular snath.

Figure 8 is a perspective showing a quickdetachable connecting means adapted to be employed with a snath and blade.

This invention relates to and is an improvement on the subject matter of Letters Patent No. 1,443,839, granted to me January 30, 1923.

In the construction of the device as shown the numeral 10 designates a scythe snath made of wood, substantially circular in cross-section and bent to desired shape throughout its length. A recess 11 is formed by cutting away a portion on the lower side of the heel of the snath 10 and an adjusting plate 12 is laid in said recess. The adjusting plate 12 is formed with two angular holes 13, 14 side by side adjacent its center and also with 1924. Serial No. 703,907.

an arcuate slot 15 adjacent its inner end portion, said slot being substantially transversely of the plate. The heel portion of the snath and the outer end portion of the ad justing plate are formed with registering notches in their side margins and a U-bolt or shackle 16 is mounted in embracing relation on the snath and plate and has its arms extending through said notches. A bar washer 17 is mounted on the arms of the U-bolt 16 and is adj ustably secured thereon by nuts 18 screwed on the extremities of the arms. The ill-bolt, bar washer and nuts constitute a clip with its curved portion uppermost and bearing on the curved periphery of the snath, the washer being parallel with and extending across the outer end portion of the recess 11. The numeral 19 designates the blade or sweep of the scythe and is formed with a sharp or cutting edge on its concaved: margin and a tongue 20 at one end extending from the sharpened side thereof substantially at right angles to the body of the blade, which tongue is adapted to lie between the washer 17 and the adjusting plate and be clamped by the washer rigidly to said plate and in association with the snath. A stud 21 is formed on and extends upwardly from the outer end portion of the tongue 20 and is adapted to be received in one or the other of the holes 13, 14 and is shaped to fit therein. The tongue 20 is of less length than the adjusting plate 12 and a bolt 22. is mounted through the slot 15 in said plate and through a hole in the snath 10 and is secured by a nut 23 hearing on'the upper face of the snath. There are twoadjustments of the blade 19 relative to the snath 10; one through oscillation of the adjusting plate 12 permitted by the relation of the arcuate slot 15 and bolt 22, and the other through. oscillation of the tongue 20 relative to the adjusting slate permitted by location of the stud 21 in one or another of the holes 13, 14. The tongue 20 engages one arm of the Ubolt 16 under strain of use and the stud 21 is received in the hole 14. The notches in the sides of the plate 12 are deep enough to provide some lateral movement of the plate 12 relative to the arms of the U- bolt 16. When the shackle is loosened (not removed), the notches still engage sufficiently to prevent the plate 12 slip-ping out of the shackle and being lost; and the stud 21 may be removed from the hole 14 into the hole 13, the back side of the tongue 20- still engaging, under strain of use, the same arm of the U-bolt. This provides for one adjustment. The bolt 22 may be loosened and the plate 12 be moved laterally, thus shifting the holes 13 and 14 laterally of the median line of the snath, thus providing for the second adjustment set forth. By utilizing these two adjustments, the operator can effect any desired relation of angularity between the blade and snath. Bored wooden nibs or handles 24:, 25 are mounted at intervals and in spaced relation in the length of the snath 10 and are secured thereto by bolts 26 extending through the bores of the nibs and through registering holes in the snath, there being a nut 27 on one end of the bolt and suitable Washers 28, 29 shaped to the surface of the snath to give stability and firmness to the assembly. The nibs or handles 24, 25 preferably extend from the snath in the same general direction as the blade 19 extends properly to relate the snath and blade to the body and arms of the operator.

In Figures 6 and 7 the snath 10 is shown as made of metal, angular or channel-shaped in cross-section and with the flanges 10 cut away at one end to permit of adjustable mounting of the adjusting plate 12 and tongue 20 on the lower side of the body of the snath. In this instance the clip is inverted and the arch thereof is flattened to fit and clamp on the lower face of the tongue 20, the arms of the clip extending through the side notches of the adjusting plate and similar notches in the flat heel portion of the snath. The same adjustments can be made with this construction as in the case of the forms first described. In securing the nibs or handles to the snath 10, the washer 28 may be omitted and a different form of washer 29' be substituted for the washer 29 to fit the snath. While a channel form of metal snath 10 is shown, it is to be understood that any angular or ribbed form may be employed.

In the quick-detachable device shown in Figure 8, the clip is omitted and a clamping yoke 16 is employed with a flattened arch adapted to engage the lower face of the tongue 20. The end portions of the yoke are turned inwardly in the same plane and are pivoted in an eccentrically arranged hole in a cam lever 30 adapted to overlay the heel of the snath. All other adjustments are retained and the tongue, adjusting plate and snath heel are connected or released by manipulation of the cam lever.

I claim as my invention- 1. In a scythe, a snath having a naked heel portion formed with notches in its op posite sides. in combination with a blade having a tongue arranged substantially parallel with the heel of said snath between said notches and a U-bolt having arms extending through said notches, said U-bolt loosely embracing and adapted to clamp said tongue to said snath. I

2. In a scythe. a snath having a heel portion formed with notches in its opposite sides, aplate arranged longitudinally of and parallel with the heel of said snath and formed with notches in its sides adapted to register with the notches in the heel of the snath, in combination with a blade having a tongue arranged substantially parallel with the plate between said notches, and a U-bolt having its arms extending through all of said notches, said U-bolt being adapted to clamp said tongue, plate and snath together.

8. In a scythe, a snath having its heel portion formed with notches in opposite sides, a

plate arranged longitudinally of and substantially parallel with the heel of the snath and formed with side notches registering with the notches in the heel of snath and also formed with a slot at one end, a bolt extending through said slot and through said snath, said plate also being formed with laterally-spaced holes adjacent said slot, in combination with a blade formed with a tongue arranged longitudinally of and substantially parallel with said plate, said tongue being formed with a stud adapted to be engaged in either of the holes in the plate, and a U-bolt having its arms extending loosely through all of said notches, said U- bolt being adapted to loosely embrace and clamp said snath, plate and tongue together, whereby said plate and tongue may be adjusted laterally and also through an arc relative to each other and to the heel of the snath.
